JAMES ALLEN HUGGINS, 015 BED SPRINGS, NORTH CAROLINA.

PLOW.

To all whom it may concern:

Be it known that I, JAMES ALLEN HUG- ems, a citizen of the UnitedStates, residing at Red Springs, in the county of Robeson and State ofNorth Carolina, have invented certain new and useful Improvements inFlows; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in plows.

One object of the invention is to provide a plow having a pivotedstandard adapted to be adjusted to regulate the. position of the bladeor shovel of the plow and having a runner bar adapted to beautomatically adjusted by the movement of the beam to correspond withthe adjusted position of the blade or shovel.

Another object is to provide a runner adapted to the purpose for whichit is designed.

\Vith these and other objects in view the invention consists of certainnovel features of construction combination and arrangement of parts aswill be more fully described and claimed.

In the accompanying drawings: Figure l is a side view of a portion of aplow embodying the invention, parts being broken away; Fig. 2 is asimilar view showing the parts adjusted to another position; Fig. 3 is across sectional view on the line 3-45 of Fig. 1; Fig. 4 is a horizontalsectional view on the line H of Fig. 1; Fig. 5 is a view similar to Fig.1 showing a modified form of the invention; Fig. 6 is a similar viewshowing the parts adjusted to another position; Fig. 7 is a crosssectional view on the line 77 of Fig. 5. Fig. 8 is a side view partly insection showing the application of the invention to a wooden beam plow.

Referring more particularly to Figs. 1, 2 and 3 of the drawings, 1denotes the plow beam which is provided near its rear end with alongitudinal slot 1. The beam 1 has a segmental downwardly curved rearportion 2 to the lower end of which is pivotally connected the rear endsof a pair of runner supporting and standard attaching bars 3.

Serial No. 635,561.

To the forward ends of the bars 3 is connected the lower end of theadjustable standard 1 of the plow. The lower portion of the standard 4is bifurcated and the upper portionprojects through the slot in the beam1 and forms a lever 5 whereby the standard is swung backward'and forwardon its pivotal connection with the bars 3 thereby tilting the plow bladeor shovel 6 to the desired angle. The upper or lever portion 5 of thestandard is provided with a spring projected pawl 7 adapted to workthrough the slot 1 and to be engaged with a segmental rack bar 8 securedto and spaced a suitable distance below the beam as shown. In thestandard and adapted to slidably en gage the space between the rack bar8 and the lower edge of the beam is a guide pin 9. Pivotally connectedto the bars 3 are pairs of runner adjusting levers 10 and 11. The lowerends of the levers 10 and 11 are curved and have formed therein curvedslots 12 as shown. To the curved lower ends of the levers 10 and 11 isconnected a runner 13 having a central upwardly extending web l3 whichis disposed between the lower ends of the levers 10 and 11 and hasarranged therein transversely disposed pins 14 which are engaged withthe slots 12 whereby when the levers are rocked in the pro-per directionthe runner will be raised and lowere The pairs of levers 10 and 11 areconnected together to operate in unison by a link or connecting bar 15.The levers 10 are considerably longer than the levers 11 and said levers10 are connected at their upper ends to the standard 1 by a link 16whereby when the standard is swung forwardly or rearwardly to adjust theblade or shovel of the plow the levers 10 and 11 will be simultaneouslyrocked through the links 15 and 16 thus raising and lowering the runner18 whereby the relative position thereof with respect to the blade orshovel is maintained. l/Vhen thus operated the runner will be raised andlowered straight or directly up and down.

In Figs. 5, 6 and 7 of the drawings is shown a slightly modified form ofthe invention. In this form of the invention the beam are pivotallyconnected the rear ends of a pair of forwardly extending parallel runnersupporting and standard. attaching bars 18 to the forward ends of whichis pivotally connected the bifurcated lower portion of a standard 19 onthe lower end of which is secured the blade or shovel 20 of the plow.The upper end of the standard projects above the beam and forms a lever21 whereby the standard is operated. The upper or lever portion 21 ofthe standard is provided with a spring projected pawl 22 which isadapted to engage a segmental rack 23 secured to the upper edge of thedownwardly curved rear end of the beam as shown. By means of the pawl.22 and rack 23 the lever and standard of the plow are secured in theiradjusted positions. Arranged through the standard 19 adjacent to thelower edge of the beam is a transversely disposed guide pin 21 whichassists in guiding and holding the standard in position. Pivotallyconnected to the bars 18 and arranged between the same are pairs of landside attaching bars 25 and 26 to the lower ends of which is pivotallyconnected a runner 27 having a central upwardly extending 'web 28 in theupper edge of which are formed notches 29 the purpose of which will behereinafter described. The levers 25 are of considerably greater lengththan the levers 26 and said levers 25 are pivotally connected at theirupper ends to the standards 19 by a link 30. The levers 25 are connectedat their upper ends to the levers 26 by a link 31 whereby said leversare caused to operate in unison when actuated by the standard. By thusconnecting the runner 27 to the levers 25 and 26, said runner will belifted by a forward circular movement when the standard is rocked toadjust the blades of the plow thus simultaneously and automaticallyadjusting the runner whereby the latter is caused to maintain the samerelative position with respect to the plow blade or shovel. When therunneris lifted in the manner described the notches in the web 28thereof engage the pivot bolts by which the pairs of levers and 26 areconnected. to the attaching bars 18.

In Fig. 8 of the drawings the invention is shown as being applied to aplow having a wooden beam 32 to the rear end of which are connected theupper ends of substan tially right angular standard attaching bars 33said upper ends of the bars being provided with series of bolt holes 3&-adapted to receive a fastening bolt 35 whereby the end of the beam maybe adjustably connected to the attaching bars. To the forward ends ofthe lower portion of the attaching bars 33 is pivotally connected thelower end of a bifurcated standard 86 the upper end of which projectsthrough a slot 37 formed in the beam 32 and has connected thereto an ardadjacent to the lower edge of said rack bar is arranged a guide pin l2.Pivotally connected to the lower horizontal portions of the attachingbars 33 are pairs of runner supporting levers 4:3 and. ist to the lowerends of which is pivotally connected a runner L5. The levers 43 areconnected at their upper ends to the standard 36 by a link 46 and saidpairs of levers 43 and a l are con nected together by a link 47 wherebysaid levers are moved in unison by the standard 36 and lever 38 thusraising and lowering the runner 4:5 to cause the same to maintain thesame relative position with respect to the shovel or blade 39 of theplow when the latter is tilted. The runner 45 is constructed in the samemanner as those described in the previous forms of the invention and inits web are formed notches 1 .8 which engage the pivot pins of the pairsof lovers 48 and a l when said runner is raised by said lever. Byconstructing and arranging the curved rack bar 41 as herein shown anddescribed said bar also forms a brace for the beam of the plow, saidbeam being pivotally connected to the upper end of the bar to permit therear end of the beam to be adjustably connected to the upper ends of theattaching bars 83 as hereinbefore described.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood witlr out requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention claimed.
